After first debuting subtle pink hair, the 24-year-old model has now chopped her locks into a very short pixie for her role in the film, Life in a Year. Delevingne teased the new look ​in an Instagram ​story on Thursday, snapping a pile of hair on the ground with the caption "Oh, no!"

Delevingne isn't the only star to switch up her look for the romantic drama. Jaden Smith, who appears opposite Delevingne in the film, got an assist from dad Will Smith in snipping off his blond dreadlocks.

Life In a Year, also starring Terrence Howard, tells the story of a 17-year-old boy who learns that his girlfriend is dying and sets out to show her their entire life together in the year she has left. The film is expected to hit theaters in 2018.

But first, Delevingne will star in the sci-fi film Valerian and the City of a Thousand Planets. See how she reacted to the high-octane trailer, below.
